Update with something new and interesting to look at:
The Spiral board based Just What I Needed number is proving a tough nut to crack. I have a simulation of the ramp generator and it's analog and digital parameters working, but have more work to do on the visualization side before I can look for clear evidence that the intended effect is being achieved.
What has been developed is place holder images which indicate the A / B bus content as determined by the 351 data.
Fed to this visualizer update is The Wait by The Pretenders, from Laserock2. While watching, please keep in mind that, if memory serves, this was a joystick heavy number, and the relevant data bits support this, see attached. I would like to pin down the correct functions that the joysticks played in this and other numbers.
Please see the video here:

I'm guessing / remembering that the right hand stick was always active, controlled by a gain dial and a quad / opposition switch. And the left hand stick did nothing unless the data set the correct rotation signal select bits. Was there a case in which offset and rotation signals came from the same stick? The console I encountered had no controls on the joystick side pods, other than the sticks themselves.
